To date, 278 crows have been submitted to and accepted
for testing by the New Jersey Department of Health and
Senior Services' Public Health and Environmental Laboratory.
A total of 15 crows -- 10 found in Bergen, 2 in Middlesex, 2
in Union and 1 in Hudson Counties -- have tested positive
for the presence of the WNV. At least one crow sample has
been submitted from all 21 New Jersey counties.

452 blood samples taken from sentinel chicken flocks
placed in all 21 counties and 405 mosquito pools collected
in every county, have all tested negative for WNV.

Blood and/or spinal fluid samples from more than two
dozen residents have been or are in the process of being
examined using either the St. Louis Encephalitis (SLE)
screening test or a test for WNV itself. The SLE test can
be conducted by private laboratories for residents with
conditions that do not fully meet established WNV testing
criteria. Since SLE and WNV are closely related viruses, a
WNV case will most likely react to a SLE test. All results
reported to date have been negative.
